I am a big believer in the KISS principle. You are familiar with that?

I think one has to ask themselves what they are attempting to accomplish and then weigh the costs.

Multi zoning off one HVAC system can be successful. There are several
components that must be brought together to make this work. This includes the best selection of zoning controls, ductwork sizing and design, correctly sized HVAC, and probably the most important would be an HVAC dealer who has demonstrated experience in this area. The last may be the difficult part.

If you decide to pursue this, ask dealer to take you to a job that he performed so you can see it.

Thanks Tiger!

Plan B: Install mini-splits.
